<< Background of the Invention >> A blasting method using an explosive is known as a method for constructing a tunnel or the like by excavating rock mass.

In this type of blasting method, usually, a face piercing process, a charge blasting process in which an explosive is attached to the piercing and explodes the explosive, a slipping process, a primary spraying process, a lock bolt attaching process, 2
A tunnel is constructed by advancing the work in the order of the next spraying process and the water stopping process and repeating this process.

By the way, when constructing a crude oil storage tank in bedrock, a large number of facets may be constructed at the same construction site in a bedrock excavation tunnel or a connection tunnel between tanks.

In such a construction situation, work management of each face is
Conventionally, a manager has been selected for each of the above-mentioned construction processes, and the selected manager has reported the work hours and the like to the on-site office by daily reports.

However, with such a work management means, the daily report is submitted on the day after the work is performed, real-time information cannot be obtained, and the progress status of the work on many facets is grasped as a whole. There was also a problem that it took time to count.

The present invention has been made in view of such conventional problems, and an object thereof is for tunnel construction in which work information can be grasped in real time and work of many facets can be easily aggregated. To provide a work management device.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a facet piercing step, a charge blasting step of blasting with an explosive attached to the piercing hole, a slipping step, a primary spraying step, Lock bolt installation process,
In the tunnel construction in which the secondary spraying process and the water stopping process are repeated in this order, the driving signal for the drilling excavator in the drilling process, the work start signal for the charging and blasting process, and the operation signal for the blaster, and the slipping process. The operation signal of the loading machine for loading the sludge on the earth and sand carrier and the entrance / exit signal of the earth and sand carrier for unloading the sludge, the operation signal of the spraying machine in the primary spraying process, and the nut tightening in the lock bolt mounting process. The drive signal of the attached machine, the operation signal of the spray machine of the secondary spraying process, and the drive signal of the nailing machine of the water stopping process are used as input signals, and the work of each process is performed based on these input signals. And a computing device for tabulating time in process order.

<< Advantageous Effects of the Invention >> According to the tunnel construction work management apparatus having the above-described configuration, electric signals corresponding to the start and end of the work are output from the drilling in each of the steps of the water stoppage. Can be grasped in real time.

Further, the signals output from the respective steps are automatically processed by the arithmetic device and tabulated in the order of the steps, so that even if there are many facets, it is possible to easily deal with them, and the tabulation becomes easy.

Embodiment Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 4 show an embodiment of a tunnel construction work management apparatus according to the present invention.

The management device shown in the same figure is applied to the tunnel construction carried out in the process shown in FIG. 1, and the tunnel construction is repeated in order, and the explosive charge is attached to the drilling to explode the explosive charge. Blasting process, slipping process, 1
It consists of a secondary spraying process, a lock bolt mounting process, a secondary spraying process, and a water stopping process.

The work management device includes signals s1 to s10 generated by the operation of various machines used in each of the above steps, and an arithmetic unit CPU that tabulates the work times of the steps to the step order based on the signals s1 to s10. It consists of and.

Explaining the details of the signals s1 ~ s10, the signal S1 sent from the face punching step includes a driving start signal and an end signal of the punching device, in addition to these signals,
For example, if the boring device is a jumbo machine that is generally adopted, signals such as the speed signal of the drilling rod, the magnitude of the impact hydraulic pressure, and the magnitude of the pressing hydraulic pressure are also included, and based on these signals. It is also possible to calculate the maximum drilling speed with the computing device CPU for more detailed control of drilling work.

The signal sent from the explosive blasting process in which explosives are attached to the hole to explode is the start signal s2 that is set at the start of explosive
And the stop signal s3 sent by the operation of the blasting machine.

The signal sent from the slipping process is the operation of the wheel loader (earth and sand loading machine) that puts the slip on the dump truck D for carrying the slip to the outside and the dump truck D.
It contains information about the operation of.

The signal s4 relating to the wheel loader includes a signal issued when the bucket is raised and lowered and a traveling time signal of the wheel loader.

Fig. 3 Signals sent by the operation of the dump truck D
It shows the details of s5.

In the figure, a pole P to which a light receiver R and its controller C are attached is erected in the vicinity of the entrance of a tunnel T having a face where the work is currently in progress.

A weight scale W is installed on the exit passage of the tunnel T.

On the other hand, the dump truck D entering and leaving the tunnel T is equipped with a transmitter S and a light emitter P.

The dump truck D entering the tunnel T drives the transmitter S to send an optical signal from the light emitter P to the light receiver R, and
The dump truck D loaded with the slip and coming out from the tunnel T stops on the weighing scale W, measures the amount of the mounted slip, and drives the transmitter S again to send a signal to the light receiver R. .

The arithmetic unit CPU that has received the signal s5 including the above contents calculates the slipping work time, the mine retention time of the dump truck D, and the total amount of the discharge slippage.

The signal s6 sent from the primary spraying step is a drive / stop signal for the concrete spraying machine, and the time required for the primary spraying step is calculated by this.

The signals sent from the lock bolt mounting process are the mortar feeder drive / stop signal s7 and the lock bolt nut tightening machine drive / stop signal s8. The tightening machine signal s8 contains the nut tightening torque. The size of can be included and used for quality control of work.

The signal s9 from the secondary spraying step is a drive / stop signal for the concrete spraying machine as in the case of the primary spraying.

The signal s10 from the water stopping process is a drive / stop signal for the nail driver.

When the signals s1 to s10 are input to the arithmetic unit CPU, the signals can be wirelessly transmitted instead of being directly connected by wire.

The arithmetic unit CPU that has received the above signals s1 to s10 performs various necessary calculation processes and displays the work time of each process step in the order of steps as shown in FIG.
